Nowadays, just about every entrepreneur relies heavily on their tablet or smartphone to run their startup. In fact, many entrepreneurs have a hard time remembering what they did before the advent of mobile devices. While most entrepreneurs are able to recognize the advantages of tablets and smartphones, some have a hard time taking full advantage of these mobile devices. If you’re not sure which apps are worth downloading, here are some of the favorite mobile apps for entrepreneurs/startups.

1. Evernote/Penultimate

Most entrepreneurs attend seminars, meetings, conferences, and talks on a regular basis. Entrepreneurs also spend plenty of time outside of the office meeting potential customers and partners as well as pitching their products and services. As you may know from experience, it can be very difficult to keep track of all these appointments. Evernote and Penultimate are two popular apps among entrepreneurs and startups that will help you keep track of all your appointments, notes, and thoughts whether you’re on the go or working in your office.

2. Asana

Even though it may be tempting to cut corners and build your startup as quickly as possible, entrepreneurs can benefit significantly from investing in their systems and structure early on. If you periodically make small improvements in project management tools and agile development, you will notice major positive changes in efficiency and productivity. Asana is a popular app that will help you organize your teams and tasks as efficiently as possible. Many entrepreneurs find that this app is powerful enough to help them run their entire business.

3. TripIt

If you’re an entrepreneur who uses their smartphone or tablet regularly, chances are you’ve heard of TripIt. Due to the nature of their work, entrepreneurs spend a lot of time traveling. Travel means dealing with last-minute delays, logistics, confirmations, and schedules. Fortunately, TripIt is an app that will help you keep all of this information organized and in one place. If you travel a lot, TripIt will likely become one of the apps that you use the most.

This app will remind you of your latest emails, notes, and conversations. Many entrepreneurs find that this app is a great way to remember all of the details, both big and small, about a client. Highrise also organizes your emails, which is a great perk for those who tend to spend hours manually organizing their email.

5. SignEasy

SignEasy is yet another popular mobile app for entrepreneurs. You can use this mobile app to sign your documents on your smartphone. This will save you time because you won’t have to print out documents, sign them, and then scan them.
